How to apply a date hierarchy template to a date item This section describes how to apply a date hierarchy template to an existing date item. When you apply a date hierarchy template to an existing date item, Discoverer Administrator automatically creates all the date items that are required to complete the date hierarchy. These new date items appear in the same folder as the original date item prefixed with the name of the original date item. If you change the date hierarchy template that is applied to a date item, Discoverer creates new date items to reflect the new date hierarchy template. However Discoverer does not remove the date items from the previous date hierarchy. If you want to remove date items from a previous date hierarchy you must remove them manually. For example, if you create the date hierarchy YYQQMM and assign it to the date item Transaction Date, Discoverer creates the following items in the folder: ■ Transaction Date YY ■ Transaction Date QQ ■ Transaction Date MM 13-12 Oracle Fusion Middleware Administrators Guide for Oracle Business Intelligence Discoverer If you then create a new date hierarchy WWDD and assign it to Transaction Date, Discoverer creates the following additional items in the folder: ■ Transaction Date WW ■ Transaction Date DD Discoverer does not delete the other three date items created previously.
